[Eisfair] ssh upgrade Warnmeldungen

[Helmut Backhaus]

Hallo Leute,
ich habe gerade auf einer Maschine ssh update gemacht.
Dabei habe ich nun doch den Key in die config gelegt.
Beim speichern der config kamen nun folgende Warnungen:

-->
- It is not recommended to use the key /etc/ssh/ssh_host_ecdsa_key anymore,
  because it is an ECDSA type key, which is classified as insecure.
- It is not recommended to use the key /etc/ssh/ssh_host_dsa_key anymore,
  because it is a DSA type key, which is classified as insecure.
- It is absolutely NOT recommended to use the key /etc/ssh/ssh_host_key
  anymore, because it is a RSA v1 type key, which is classified as
  extremely insecure.

  Please navigate to the directory /etc/ssh and move the listed key files
  (.._key and .._key.pub) to a different directory, restart the sshd process
  by executing the command '/etc/init.d/sshd restart' and make sure that you
  are still able to access your server by opening a second SSH shell.

Das war mir schon einmal aufgefallen, habe nur vergessen hier zu fragen
... :-))

Was soll mir das sagen?
Habe ich etwas falsch gemacht?

Beim einrichten von ssh per Key halte ich mich eigentlich immer an diese
